My story is very personally and don't want to speak of it, anyways here's my question. My last period ended on July 27th and between the time of August 9- 25 I took 4 pregnancy tests and all came out negative so i waited a week and went to the doctor. Took blood and the test came back negative so I thought I was good, and maybe it was just stress for the reason my period was still late. Then I went to the doctor again and told them I still hadn't received my period, blood was drawn, again, my test was negative and now today I'm still waiting for it... It's been 66 days. Do you guys have any thoughts about what it could be?
